Talks between Iran, world powers on nuclear issue to resume Sept. 18 in New York

EU foreign policy chief Catherine Ashton speaks during a press conference at the end of an informal meeting of the EU Foreign Affairs Ministers, in Milan, Italy, Saturday, Aug. 30, 2014. European Union leaders are set to decide who will be the 28-nation bloc's foreign policy chief for the next five years, with Italy's top diplomat Federica Mogherini widely seen as the front-runner for the prestigious job. The decision on incumbent Ashton's successor comes as the crisis at the EU's eastern border pitting Ukraine against Russia poses one of the biggest foreign policy challenges for the bloc in decades.

Iranian President Hassan Rouhani gives a press conference in Tehran, Iran, Saturday, Aug. 30, 2014. Rouhani called Western sanctions an "invasion" on Saturday after Washington imposed existing sanctions on more than 25 businesses, banks and individuals suspected of working to expand Iran's nuclear program, support terrorism and help Iran evade U.S. and international sanctions. Iran's state TV also said the move violated an interim agreement reached with world powers under which Western nations agreed to ease sanctions in exchange for Iran curbing its nuclear activities. However, Friday's action did not constitute an expansion of the sanctions regime. (AP Photo/Ebrahim Noroozi) (The Associated Press)
